A century ago, Pierre Cartier traveled the world and brought diamonds straight to homes. With the pandemic discouraging customers from going out to stores, high-end jewelers are once again making a mint through house calls, with sales climbing as much as 300%

A popular spin on this pandemic-inspired activity includes inviting local jewelers to intimate outdoor gatherings, creating mini backyard jewelry-shopping parties. 

Jewelers transporting diamonds and watches worth thousands of dollars also increases risk of theft. To ensure smooth delivery and exchange, there’s an opportunity for an Uber model of on-demand security. GettGuard is one such app available in France, but the space is still up for grabs elsewhere.
